CAN-CAPPING MACHINE.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed March 5, 1906. Serial No. 304,181.

Be it known that I, SAMUEL HooKEY, a citizen of the United States, and a resident of Wyandotte, in the county of Wayne and State of Michigan, have invented a new and Improved Can-Capping Machine, of which the following is a specification.

My invention relates to an improved mechcapping mechanism and in improved mechanism for capping cans.

My invention consists in an improved'seam- I ing-head for cans wherein pivoted levers that carry the dies are moved into operative poition by means of pressure on their outer en s.

It consists, further, in improved means for carrying the cans under the seaming-dies and for holding them in position.

lt consists, further, in improved means for assembling the head and can-body.

In the accompanying drawings, which illustrate a machine embodying my invention, Figure 1. is a side view ofthe machine with parts broken away for clearness. Fig. 2 is a view looking up at the feeding mechanism. Fig. 3 is a detail of the same. Fig. 4 is a plan, and Fig. 5 an elevation, of the feeding mechanism. Figs. 6 to l0, inclusive, are enlarged details of the same. Figs. 11, 12, and 13 are details of the head-seaming mechanism on a somewhat larger scale than in Fig. 1.

Similar reference characters refer to like artsA throughout the several views of the j wings.

i, n the machine shown in the drawings the bodies and heads of the cans are fed in separately. The bodies slip under and engage their respective heads. The two are fed to a seaming mechanism, and all then travel awayfrom the machine.

The forming of the bodies and heads forms no part of this invention. These are conveyed to the machine, the bodies by means clined chute.

The machine is built as follows:

The table 1, rectangular in form, is supported by the legs 2. ecured to the table is the frame 3, in which are journaled the main shaft 4, the auxiliary horizontal shafts 5 and 6, and the vertical stationary shaft 7. The main shaft has the tight and loose pulleys l and 9 on its outer end to receive the drivingbelt. On its inner end is a bevel-gear 10, which transmits motion to the crimping-head through the bevel-gear 11. a die-head 12 on its lower end, which diehead has a bead 13, against which the dies press the flange of the can-head during the process of crimping. The crimping-head is formed as follows 01"imptng-head.-Revoluble on the shaft 7, which carries the die-head 12 at its lower end, is the sleeve 14, having the'bevel-gear 11 at its upper end and the bearing-fiange 15 at the lower. (See Figs. 11, 12, and 13.) Secured on this sleeve is the die-carrier, which has four arms 17 to carry the die-levers 23. The hub of the die-carrier is formed of four parts, so that it may be assembled on the sleeve 14 by means of the screws 20 and the clampc 21, which hold the segments 18 in place. The set-screws 26, which extend down ard con- -tact with the flange 15, also serve to support the die-carrier. Vrivoted on the arms 17 are the die-levers 23, which have pins 24 secured in their lower ends, upon which pins are mounted the revoluble crimping-dies 25. Slidably mounted on the sleeve 14 is the spider 19, which carries the screws 22 and springs 27 at the ends of its arms, which sp1- der when depressed pushes the dies inward against the iianofe of the can-head and when raised pulls thelevers outward by means of the springs 27. The spider 19 is adapted to be freely moved up and down by means of the lever 29, which is pivoted on the frame 3 at 30, the forked front ends 31 of which are provided with screws 32, that enter the slot 33 in the. hub of the spider 19. The rear end of the lever 29 is forked and has arms 34, which arms are provided with set-screws 35, adapted to contact with the lugs 36 on the vertically-movable actuator 37. This actuator carries the roller 38, which contacts with. the cam 39 on the shaft 6. The spring 4U holdsthese parts in contact and counteracts the weight of the spider. lever 29, actuator 37, the cam 39, and the 1ntermediate parts constitute the die-operating mechanism.

Slidably mounted for vertical movement only is the can-support 41, which has a depending stem 42 passing through the depressed portion 43 of the table 1.. rlhe lower end of this stem rests on thead1ust1ng-screw The shaft 7 has The spider 19, the

44 in the end of the lever 45, the screw 46 in the other end of this lever contacting with the lower end ofthe slidable member 47. In

the upper end of this slidable member is theA roller 48, which contacts with the face of the.

cam 49 on the shaft 6.

The operation of the parts thus far described is as follows:v The shafts being in motion, the die-carrier and dies will be revolved by-the main shaft 4, which also drives the shaft 6 through the reducinggears on the shafts 4, 5, and 6. At each revolution of the shaft 6 the cam 49 will press up the can-support 41 and the can thereon, and at the same time the spider 18 under the action of the cam 39 will swing the dies 25 inward to crimp the flange 50 of the can-head 51 around the can-body 52. When the faces of the cams recede, the support 41 will lower, while the cam 39 permits the spider to swing out the dies through the action of the springs 27. The sealed can is then moved away and another can body and head placed on the support.

T he coneeyers.-The filled can-bodies 52 are placed on the conveyer-belt 53, which extends around the idle pulley 54 and drivingpulley 55. A shaft 56, journaled in bearings 57 at the side of the table, carries the chainwlieel 58, which connects to the chain-wlieel 59 on the shaft 60, mounted beneath the table by means of the chain 61. A vertical shaft 62 carries a miter-gear 63, which engages the miter-gear 64 on the end of the shaft 6, and another bevel-gear 65,` which engages the bevel-gear 66 on the shaft 60 to drive the same. The can-bodies are carried by the belt 53 up to a stop 67, Fig. 4, which positions them for the feeding mechanism. The sealed cans are carried from the machine on a belt carrier 68.

The heads 51 arrive at the machine by means of the inclined chute 69, which has a guard-plate 70, which prevents the heads fi'oni jumping out of the chute.

The feeding mechanism-A notched disk or star wheel 71 is adapted to move the cans and heads under the crimping mechanism. It is unnecessary for the wheel to hold the cans during crimping operation, as this is done by the can-support 41 and the die-head 12. The star-wheel is mounted on the upper end of the shaft 72, which receives regular intermittent motion as follows, (see Figs. l, 2, and 3:) This star-wheel has a series of pockets or notches 73 to receive the cans, e ual in number to the notches in the ratchetw ieel 74, secured to the shaft 72. The pawl 75 and the spring 76 to hold the pawl in engagement are carried by the pawl-carrier plate 77, which is revoluble on the shaft 7 2. The link 78 connects the plate 77 to the lever 79, pivoted at 80, which lever carries the roller 81a, that contacts with the cam 81 on on the shaft 7 '2.

the shaft 62.

ing-dies. The parts just described are returned to normal by the strong spring 100.

To position the star-wheel accurately and hold it in place, the loiigitudinallyanovable bar 82 is employed. This bar carries a tooth 83, that engages in notches 84 in the disk 85 The har is supported by the nuts 86 and 87 on the ends of the shafts 72 and 62. The tooth 83 is normally held in a notch by the spring 88, which connects to the cross-bar 89; but at each revolution of the shaft 62 the tooth 83 is withdrawn by the cani 90 on the shaft 62 acting against the upwardly-turned lip 91 on the end of the bar. The ends of the bar are slotted, as shown in Fig. 3,

The cans are moved off the belt 53 by means of apusher into apoeket 73 of the starwlieel at the end of each operation of the parts of the feed mechanism already described and while the can-head in the. pocket opposite is being crimped. Depending from the table is a guide 93, and extending outward from the table is a rod 94. The pusher consists of a plate 95, having an upiurned portion 96, that engages the can, andthe downturned part 97, which carries one end of the rod 98. 'lhis rod carries a finger 99 and one end of the spring 101, the other end of which spring iscarried by the arm 102 on the outer end of the rod 94. 'lhe rod 98 is slidahle in the bracket 93 on the table 1. The part 97 of the pusher slides on the rod 94. Pivoted on the crosslar 89 is the lever 103, which connects to the lever 79 by the link 104 and at the upper end has attached a link 105, which is adapted to actuate the pusher. The outer end ofthis link carries the hook 106, which engages the finger 99 on the rod 98 and carries it, together with the pusher, inward whenever the cam 81 permits the lever to return from its operation of turning the shaft 72 under the pull of the spring 100;

Secured to the bottom of the table is the post 107, which carries the pin 108, which passes through the slot 109 of the link 105, and thus supports it. rlhis pin carries a cam 110 at one end and a cross-liar 111 at the other. Springs 112, mounted on rods 113, slidable in the cross-liar 11.1 ,hold the cross-li ar 114 outward against the link 105. The link is provided with a cam 11.5, which when it contacts with the cani 110 pulls the hook 106 out of engagement with the finger 99 and permits the spring 101 to return the can-pusher to normal position.

It will be seen that the pusher is springoperated throughout, receiving its operative movement from the strong spring 100 and its return movement from the weaker spring IIO IZO

'mounted on pins 1.35,

In case a can is misplaced so that it does not properly enter a pocket in the star-wlieel the spring 100 will not pull the pusher to its full stroke. This will prevent the spring piilling the pawl-carrier plate 77 its full stroke and the pawl will not engage the next tooth of the ratchet-wheel 74, and thus no damage will be done, the feeding mechanism remaining idle until the attendant corrects the difficulty.

Referring Anow to Figs. 6 to 10, inclusive, a device is there shown that governs the assembling of the'ean body and head and indents the iiange on the head at two points, so that it will not slip oli during the subsequent movements. Projecting upward from the center of the shaft 72 is a stud or pin 120, which supports one end of the plate 121, the post 122, projecting upward from the table 1, serving as the other support. The pin 120 is revoluble in the plate, while the connection between the post 122 and the plate is rigid, but adjustable. plate is a guide-finger carrier in the form of a plate having an upwardly-extending portion 123, slightly bent toward the rear, and feet 124, which are secured to the plate 121. Fingers 125, pivoted at 126, are positioned by the screws 127 and held together by the spring 12S. These fingers extend down, as shown in Figs. 7 and 8, and guide the heads 51 of the cans. The normal distance between the lower ends of the lingers is slightly less than the diameter of the can-heads, so that the heads will be prevented from slipping too far down the incline or chute 69. The position of the head thus held is such that when a can-body has been placed in a pocket 73 of the star-wheel 71 the movement of the starwlieel will cause the body to pick up its head in the manner indicated in Fig. 8. tongue 129, loosely held at 130 and normally. depressed by the spring 131 on the rod 132, is adapted to hold the head on the body during this picking-up movement. The edge of the plate 121 and the guide-finger carrier 123 are slotted to permit the vertical movement of this tongue.

Beneath and secured to the plate 121 are curved guides 133, which prevent the can bodies and heads from moving out of the pockets 73 until after the flanges on the heads are indented by the rollers or dies 134, as shown in Fig. 9. This indenting prevents the heads from jumping oil the bodies when relieved from the pressure of the curved plate 13 6, which is cai'- ried between the guides 133 by the pins 137 in the yokes 13S. The springs 139 on these pins tend to hold this plate downward. f liter the iianges on the heads have been indented the cans are carried onward; by the star-wheel, being prevented from -sliding outward by the guard 140, Fig. 4, which is a con- At the forward edge of this.

tinuation of the stop-plate 67. The heads are then crimped by the dies 25, and the sealed cans are guided out of the star-wheel pockets by the arm 141, secured to the table, and the cans will push each other onto the conveyer 68.
